## SKILL.md
`Application` is the convenience wrapper that owns a renderer, a root `stage` Container, a canvas, and the Ticker/Resize plugins. In v8 the constructor takes no arguments; all configuration is passed to the async `app.init()` call which instantiates the renderer via `autoDetectRenderer`.
## Quick Start
```ts
import { Application } from "pixi.js";
const app = new Application();
await app.init({
resizeTo: window,
background: "#1099bb",
antialias: true,
preference: "webgl",
autoDensity: true,
resolution: window.devicePixelRatio,
});
document.body.appendChild(app.canvas);
```
**Related skills:** `pixijs-core-concepts` (renderers, render pipeline), `pixijs-ticker` (render loop detail), `pixijs-scene-container` (working with `app.stage`), `pixijs-environments` (non-browser setups).
## Core Patterns
### Lifecycle: construct, init, render, destroy
```ts
import { Application } from "pixi.js";
const app = new Application();
await app.init({ width: 800, height: 600 });
document.body.appendChild(app.canvas);
// ... run scene, ticker drives app.render() automatically ...
app.destroy(
{ removeView: true, releaseGlobalResources: true },
{ children: true, texture: true, textureSource: true },
);
```
- `new Application()` allocates the instance but creates nothing. Options passed here are ignored with a v8 deprecation warning.
- `app.init(options)` is async. It builds the renderer, wires up plugins, and must complete before you can use `app.canvas`, `app.renderer`, or `app.screen`.
- The TickerPlugin calls `app.render()` every frame once init resolves (unless `autoStart: false`).
- `app.destroy(rendererDestroyOptions, stageDestroyOptions)` — the first argument forwards to `renderer.destroy()`. Pass `true` or `{ removeView: true }` to remove the canvas from the DOM. Add `releaseGlobalResources: true` to drain global pools (batches, texture caches) when tearing down and re-creating an app in the same tab; omitting it is the usual cause of flickering and stale textures after a re-init (see `pixijs-performance`).
### Key init options
```ts
await app.init({
width: 800,
height: 600,
background: 0x1099bb,
backgroundAlpha: 1,
antialias: true,
resolution: window.devicePixelRatio,
autoDensity: true,
preference: "webgpu",
autoStart: true,
sharedTicker: false,
resizeTo: window,
canvas: document.querySelector("#game-canvas") as HTMLCanvasElement,
});
```
For every option — view/canvas, background, renderer preference (including the array form), ticker, resize, culler, events, accessibility, WebGL/WebGPU context flags, Graphics bezier smoothness, GC, and per-renderer overrides (`webgl` / `webgpu` / `canvasOptions`) — see [references/application-options.md](references/application-options.md).
### Application properties
```ts
app.stage; // root Container; add all display objects here
app.renderer; // the WebGL/WebGPU/Canvas renderer instance
app.canvas; // the HTMLCanvasElement (insert it into the DOM yourself)
app.screen; // Rectangle describing the visible area in CSS pixels
app.domContainerRoot; // HTMLDivElement that holds DOMContainer overlays
```
`app.stage` is a plain `Container`. For scene graph detail (transforms, addChild, destroy) see `pixijs-scene-container`. For renderer-level operations (extract, generateTexture, custom systems) see `pixijs-core-concepts` and `pixijs-custom-rendering`. `app.domContainerRoot` is the `
` that the renderer uses to host `DOMContainer` overlays; append it next to `app.canvas` when you need DOM elements pinned to scene nodes (see `pixijs-scene-dom-container`).
### ResizePlugin
Set `resizeTo` at init (or reassign `app.resizeTo` later) to have the plugin listen for the `resize` event and call `renderer.resize()` with the target element's client size. Combine with `autoDensity: true` and `resolution: window.devicePixelRatio` for high-DPI output.
```ts
await app.init({ resizeTo: window });
app.resizeTo = document.querySelector("#game-container") as HTMLElement;
app.resize(); // immediate resize to the target's current size
app.queueResize(); // defer the resize to the next animation frame
app.cancelResize(); // drop a pending queueResize
```
The plugin keeps the canvas matched to the target. `app.screen` and `app.canvas.width/height` update in response; read them after the resize to place UI.
- `app.resize()` — immediate synchronous resize.
- `app.queueResize()` — coalesces rapid calls by deferring to the next frame; internally used by the `window.resize` listener to avoid redundant work.
- `app.cancelResize()` — cancels a queued resize. Call this before tearing down your own layout code that triggered `queueResize`.
### Ticker basics
The TickerPlugin creates `app.ticker` and registers `app.render()` on it at `UPDATE_PRIORITY.LOW`. Control the loop with `app.start()`/`app.stop()` and add callbacks with `app.ticker.add` / `app.ticker.addOnce`:
```ts
app.ticker.add((ticker) => {
sprite.rotation += 0.01 * ticker.deltaTime;
});
app.ticker.addOnce(() => {
console.log("runs once on the next frame, then removes itself");
});
app.stop(); // pause the render loop (e.g. tab hidden)
app.start(); // resume
```
The callback receives the `Ticker` instance; read `ticker.deltaTime` for a frame-rate-independent multiplier (~1.0 at 60fps), `ticker.deltaMS` for real milliseconds, or `ticker.FPS` for the current frame rate. See `pixijs-ticker` for priorities, FPS capping, `onRender`, shared vs private tickers, and the v8 callback signature change.
### Manual render loop
```ts
await app.init({ autoStart: false, width: 800, height: 600 });
document.body.appendChild(app.canvas);
function frame() {
updateScene();
app.render();
requestAnimationFrame(frame);
}
frame();
```
`autoStart: false` prevents the TickerPlugin from starting the ticker automatically. Call `app.render()` yourself (or `app.renderer.render({ container: app.stage })` for the same effect). If you still want registered ticker callbacks to fire, call `app.ticker.update()` inside your loop before `app.render()`.
### CullerPlugin (opt-in)
The CullerPlugin skips rendering containers that fall outside `app.renderer.screen`. It isn't registered by default; add it before creating your app:
```ts
import {
Application,
Container,
Sprite,
extensions,
CullerPlugin,
Rectangle,
} from "pixi.js";
extensions.add(CullerPlugin);
const app = new Application();
await app.init({ width: 800, height: 600 });
const world = new Container();
world.cullable = true; // this container is culled when its bounds leave the screen
world.cullableChildren = true; // default; set `false` to skip recursing into children
const tile = Sprite.from("tile.png");
tile.cullable = true;
world.addChild(tile);
app.stage.addChild(world);
```
Containers are not culled unless `cullable` is set. Override the default bounds check with `container.cullArea = new Rectangle(x, y, w, h)` when child bounds are expensive to compute. The plugin wraps `app.render()` so `Culler.shared.cull(app.stage, app.renderer.screen)` runs before every frame. See `pixijs-performance` for when culling pays off.
### Custom Application plugins
Extend `Application` by registering a class with `static init`, `static destroy`, and `static extension = ExtensionType.Application`. Both methods are called with `this` bound to the Application instance, so `this.renderer` and `this.stage` are available.
```ts
import {
Application,
ExtensionType,
extensions,
type ApplicationOptions,
} from "pixi.js";
class FpsOverlay {
public static extension = ExtensionType.Application;
public static init(this: Application, options: Partial
) {
// runs inside app.init() after the renderer is created
// attach props/methods to `this` to expose them on the app
}
public static destroy(this: Application) {
// runs inside app.destroy() — tear down anything you attached
}
}
extensions.add(FpsOverlay);
```
Plugins initialize in registration order and destroy in reverse. To add typed options for your plugin, extend `PixiMixins.ApplicationOptions`:
```ts
declare global {
namespace PixiMixins {
interface ApplicationOptions {
fpsOverlay?: { visible?: boolean };
}
}
}
await app.init({ fpsOverlay: { visible: true } });
```
The built-in `ResizePlugin`, `TickerPlugin`, and opt-in `CullerPlugin` all use this same contract. If you set `skipExtensionImports: true`, register the built-ins you need yourself (`extensions.add(ResizePlugin, TickerPlugin)`).
## Common Mistakes
### [CRITICAL] Passing options to the constructor
Wrong:
```ts
const app = new Application({ width: 800, height: 600 });
document.body.appendChild(app.canvas);
```
Correct:
```ts
const app = new Application();
await app.init({ width: 800, height: 600 });
document.body.appendChild(app.canvas);
```
In v8 the `Application` constructor takes no arguments. Options passed there are ignored and log a deprecation warning; the renderer is only created inside the async `init()` call.
### [HIGH] Using app.view instead of app.canvas
Wrong:
```ts
document.body.appendChild(app.view);
```
Correct:
```ts
document.body.appendChild(app.canvas);
```
`app.view` was renamed to `app.canvas` in v8. The old getter still works but emits a deprecation warning.
### [MEDIUM] Touching app.canvas or app.renderer before init resolves
Wrong:
```ts
const app = new Application();
document.body.appendChild(app.canvas);
app.init({ width: 800, height: 600 });
```
Correct:
```ts
const app = new Application();
await app.init({ width: 800, height: 600 });
document.body.appendChild(app.canvas);
```
`app.renderer`, `app.canvas`, and `app.screen` are only populated once the `init()` promise resolves. Accessing them earlier returns `undefined`.
